Safety Functions

Sensoface sensor monitoring

Sensoface provides informationon the sensor condition. A sad“Smiley” indicates that there is aSensocheck message. Sensocheck alerts for significantsensor polarization or excessivecable capacitance caused by anunsuitable cable or a cable that istoo long. Sensocheck can beswitched off. With Sensocheck

switched off, no friendly Smiley ap-pears.

For more detailed information, see chapter “Diagnos-tic, Maintenance and Cleaning” (Pg. 25).

GainCheck manual instrument self-test

Simultaneously pressing � and �starts the manual instrument self-test.

A display test is carried out, the software version isdisplayed and the memory and measured valuetransmission are checked.

Automatic instrument self-test

The automatic unit self-test checks the memory andthe measured-value transmission. It runs automati-cally in the background at fixed intervals.

Operation

18

Outputs

Current loop (4 to 20 mA)

The current loop transports power to and output sig-nals from the Transmitter. The current is controlledby the process variable selected in the configuration.The current characteristic can be configured as lin-ear or logarithmic curve for conductivity and resistiv-ity.The current beginning and end can be set to repre-sent any desired value.If LIN (linear characteristic) is chosen, the minimumspan is 5% of the selected process variable / mea-surement range. If LOG (logarithmic characteristic) ischosen, the minimum span is one decade within thechosen range.To check connected peripherals (e.g. limit switches,controllers), the loop current can be manually speci-fied (see Pg. 27).

HART communication

The APT2000CC-H-.. Transmitter can be remotecontrolled via HART communication. It can be con-figured using a handheld terminal or from the controlroom. Measured values, messages and device iden-tification can be downloaded at any time. This al-lows easy integration also in fully automatic processsequences.

For more detailed information, refer to the HART

Command Specification.

Alarm

During an error message the alarm LED flashes.Alarm response time is permanently set to 10 sec.

Error messages can also be signaled with a 22 mAsignal via the loop current (see Configuration,Pg. 20).

Configuration

The instrument arrives from the factory configuredand ready to operate as a conductivity transmitter.This section provides detailed procedures for chang-ing operation values for specific applications.

Activate with ��change parameter with � and �, confirm/continue with ��, end with ��

Mode code “1200”

During configuration the Transmitteris in the Hold state, the loop currentis frozen.

When the configuration mode is exited, the Transmit-ter remains in the Hold state for safety reasons. Thisprevents undesirable reactions of the connected pe-ripherals (e.g. limit switches, controllers) due to in-correct settings. The measured value and Hold aredisplayed alternately. Now you can check whetherthe measured value is plausible and specifically endthe Hold state with ��. After a relax time of20 sec (for measured value stabilization) the Holdstate is ended.

The configuration parameters arechecked during the input. In thecase of an incorrect input “ERR” isdisplayed for 3 sec. The parame-ters cannot be stored with ��until the input has been repeated.

Calibration

The conductivity value is determined by multiplica-tion of the cell constant with the measured conduc-tance. The cell constant consists of the sensor fac-tor (SF) multiplied by the cell calibration factor (CF).The sensor factor is the nominal value for the definitesensor type. It is set in the configuration mode (seePg. 19). The cell calibration factor (factory setting1.0) is changed in the calibration mode. If the cellcalibration factor of the sensor in use is known, it canbe entered directly. Furthermore, the cell calibrationfactor can be determined with a known calibrationsolution under consideration of the temperature.

The cell calibration factor will not bereset by a new selection of the sen-sor factor in the configurationmode.

Activate with ��,confirm/continue with ��, abort with �� ➜ ��

During calibration the Transmitter isin the Hold state. The loop currentis frozen.

When the calibration mode is exited, the Transmitterremains in the Hold state for safety reasons. Thisprevents undesirable reactions of the connected pe-ripherals (e.g. limit switches, controllers) due to in-correct settings. The measured value and Hold aredisplayed alternately. Now you can check whetherthe measured value is plausible and specifically endthe Hold state with �� or repeat calibration with�� If you end the Hold state, the Transmitter willreturn to measuring mode after a relax time of 20 sec(for measured value stabilization).

Calibration by input of cell calibration factor (CF)(CAL 1100)

Activate calibration by pressing the�� key.Using the � , � keys entermode code “1100” and then press��.

Using the � , � keys enter the ca-libration factor. The lower displayshows the conductivity value.

A change in the calibration factoralso changes the conductivityvalue.

When there has not been an entryfor approx. 6 sec, conductivity andtemperature are displayed alter-nately.

Press �� to confirm the cali-bration factor.

The Transmitter remains in the Holdstate. You can end the Hold statewith ��. After a relax time of20 sec (for measured value stabi-lization) the Transmitter returns tomeasuring mode.

Hold state

The Transmitter will enter the Hold state under thefollowing conditions:

For calibration: Mode code 1015Mode code 1100Mode code 2222

configuration: Mode code 1200Mode code 5555

The loop current is frozen at Last or Fix (configura-tion Pg. 20). If the calibration or configuration mode is exited, theTransmitter remains in the Hold state for safety rea-sons. This prevents undesirable reactions of theconnected peripherals (e.g. limit switches, control-lers) due to incorrect settings. The measured valueand Hold are displayed alternately. Now you cancheck whether the measured value is plausible andspecifically end the Hold state with ��.The loop current will remain frozen for another20 sec (relax time). This ensures that the Transmittercan adjust to the new measured value. After that, theTransmitter returns to measuring mode.

During error conditions the Holdstate will not be active.
